HEEL-MAILING MACHINEg SPECIFICATION forming part of Letters Patent No. 378,617, dated February 28, i888.

Application filed December 9, 1887. Serial No. 257.366.

.To all whom it may concern:

Be it known that I, FREEnonN FRAYMOND, 2d, of Newton, in the countyT of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel Compressing and Attaching Machines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a heel compressing and attaching machine organized to compress the heel-blank and to drive into it two gangs or groups ofnails for the purpose of attaching it and for the purpose of securing a finish to the outer surface thereof, for increasing its wear, and for attaching the top lift.

It further relates to a machine organized to first nail the heel-seat of the boot orshoe, to then compress the heel-blank thereon, and to then drive a gang of attaching-nails through the heel-blank into the soles ofthe boot or shoe.

It further relates to various features of construction and organization, all of which will be hereinafter referred to.

The invention is in some respects an improvement upon that described in my Patents Nos. 344,499 and 346,125; but this invention varies from those described in the said patents, as well as the other of my pending applications, in that it involves the employment of a heel-compressing device with apparatus or mechanism for driving two gangs or groups of nails or slugs, which is movable in relation to the heel-compressing mechanism, so that one gang of nails may first be driven into the heel end of the outsole, the heel then compressed,and a second gang or group driven into the compressed heel, or the heel-blank first compressed and two gangs or groups of nails or slugs driven successively by mechanism into the heel-blank while it is held compressed.

In the drawings, Figure l is a View, principally in vertical central section, taken from front to rear of my machine, and showing the central and upper parts thereof, representing the position of the parts before the heel-blank is compressed. Fig. 2 is a view, part in front elevation and part in vertical section, representing, substantially, the same parts as those (No model.)

shown in Fig. l and the position which they l bear to each. other before the heel-blank is compressed.4 Fig. 3 is a view upon the section shown in Fig. l, representing the position of theparts upon the completion of the compressing of the heel-blank. Fig. i is a View upon the same section representing the position of the parts after the compressing of the heel-blank and the driving of one gang of attaching-nails therein. Figs. 5, 6, 7, 8, 9, and 10 are detail views.

Referring to the drawings, A is the crosshead,which has a reciprocating movement imparted to it, preferably by means described in Patent No. 316,894, granted to Henry A. Henderson. It carri es a revolving head, A', which preferably has an arm supporting a pressureblock, A2, an arm supporting a gang of awls, A3,`

an arm supporting a gang of drivers, A4, an arm supporting a second gang or group of awls, A5, an arm supporting a second gang or group of drivers, A, and a top-lift or heel spanker, Al.

B is the bed of the machine. Upon it is mounted a jack, C, which has a sliding movement thereon in suitable ways, and which also has the jack-spindle c, vertically adjustable, and carrying a last or work support, c. (Shown in dotted outline in Fig. l. The bed B also supports a post, B, having a circular column, B2, upon which is mounted a table, B3. This table has a sleeve, B4, which surrounds the post B2, and it has a vertical nievement on the post in opposition to the spring B5. It is also adapted to be rotated or turned upon the post. It preferably has three arms or projections: rst, the arm B, which supports a templet, Bl; second, the arm B3, which supports a templet, B, third, the arm B1", l

which supports a top-lift-holding device which is similar to that described in my said' Patent No. 346,125. (See Figs. 2, 6, and 8.) The templets B7 B are removable from their respective holding-arms. There is arranged to be moved horizontally upon the table B3 a sliding plate, D, which carries at one end the I prefer that the arms B, BB, and Bl be IOO `formed integral with the table B3 and sleeve B4, and that the arms BG B8 extend radially from opposite sides of the table and upon substantially the same line, and that the arm B1 extend at a right angle from a horizontal line taken through Vthe two arms or projections BG BB. The arms B0 B8 afford supports for the removable templets, and the templets, or either of them, may have any desired arrangement of holes--that is, they may have a full line or row, or a double line or row, or a full line with a short exterior or interior line for slugging-or one of the templets-that is, the templet last used-may have a line of sluggingholes only, and, if desired, the templet may be made so as to be reversed in its holderthat is, so as to bring its under surface uppermost. This will enable the templet to be used somewhat longer, and in a slugging-plate will enable the holes to be used both for right and left slugging.

There is mounted upon the sleeve B4 a plate, E, which has a vertical movement upon the sleeve, being movable downward thereon in opposition to the pressure of the spring E, which bears upon a collar or projection, E2, at the lower end of the sleeve and against the under surface of the plate E. The plate, however, does not rotate with the sleeve, having only a vertical movement thereon7 and it is prevented from rotating by means of the stud or pin E3, which enters the hole E4 in a backward extension of the plate, the plate extending forward from the sleeve to form two arms, E5 E, which are separated from each other by a space sufficiently large to receive a die, El. This die may be solid in one part, or it may be in two parts, as represented, and it is carried. by the arms E5 E6, so as to be movable vertically therewith. When it is made in two sections, E8 E9, I prefer that they be shaped substantially as represented in Figs. 2 and 10. The section EB has an extension which fits a recess, El, in the arm E5, and the section E9 has an extension which fits a recess, E, in the arm E6. The two sections of the die are also made movable in relation to veach other by means of the screws E, which act to keep them closed during the compression of the heel-blank and to permit them to be separated upon the removal of the heel-blank therefrom.

In operation, the heel-blank having been placed in the die-cavity, and the jack having the boot or shoe mounted upon thelast brought into operative position in relation thereto, substantially as shown in Figs. l and 2, the heel-blank is compressed in the die by the verv tical movement of the die downward in relation to the last orheel-support c. This movement is produced either by bringing one of the templets over the top of the die-block and bringing the pressure-block into position over the templet and causing the machine to make a reciprocation, or by causing the pressureblock to act directly upon the upper surface of the die-block to move the die down. In

the first-named case both the die-supporting plate E and the table B3 are moved vertically and both are locked automatically in their lowest position. In the latter case the die and its supporting-plate E only are moved vertically and the plate locked automatically in its lowest position. In this event the templet which it is desired to use is then swung around into position and the gang of awls which operate therewith reciprocated. This causes the table B3 to be moved downward and automatically locked in its lowestposition and the awlholes to be formed in the heel-blank. The

ynails are then delivered to the holes of the templet by the forward movement of a nailcarrier in relation thereto andare driven. To drive a second gang of nails into the heelblank,or to attach a top lift and to then drive a second gang of nails, the table B3 is unlatched and forced upward by itsspring without, however, unlatching the die-holding plate E. This p'ermits the table B3 to be rotated to bring the other templet into operativel position in relation to the heel-blank, or to bring the top-lift holder into position over it, and a second gang or group of nails is then driven or the top lift attached, and then the second gang or group of nails driven. v table B3 is of course moved downward by the awl-block and automatically locked, as in the iirst driving, and the nails fed and driven,and it is then released', as before, and turned to bring the original templet into operative position. The die-block plate Eis then released, the section of the dies having first been released by turning their holding-screws sufficiently to permit them to leave the heel.

To latch the die-holder plate E in its lowest position, I have represented the plate as connected with the rod G by means of the long links g and the arms g. These arms and the lower ends of the links are connected by a horizontal cross-rod, g2, and the latch g3 at the end of a lever, g4, is arranged to automatically engage the cross-rod g2 by shutting over the same upon the end of the downward movement of the plate E and of the cross-rod, and it is held from closing upon the same when the plate E is in its highest position by a bar or extension, g5. (See Fig. l.) The releasinglever G is pivoted at go, and its handle is suttlciently long to act as an overbalance, causing the latch g3 to be moved into position auto- -matically; but as a rule I prefer to use, in adlowest position by means of the lever H, which is pivoted at h and connected by the rod h with the' table B3. This lever operates as a handlever, whereby the table is depressible by hand, and it is automatically locked in its lowest position by a latch, h2, (see Figs. 5 and 7,) which In this second driving the IOO IIO

IIS

is formed by the arm h3 of the releasing-lever if. rIhis arm has an extension, h5, which bears against the edge of the lever, being held there by the spring h6, so that upon the falling of the lever H below the latch said latch is caused to be drawn over the lever to lock it down. I would say, however, that I do not confine myself to said forms of latching devices for locking the table E and the plate B3 in their lowest position.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
